Abstract
Three fertilizers containing various amounts of citrate- and water-soluble phosphates were compared with superphosphate and rock phosphate in field and greenhouse experiments.Yield curves and equations were calculated and drawn and, from these, availability coefficients were calculated.The phosphate availability of the fertilizers was reduced as the relative amount of water-soluble phosphate they contained was reduced. However, in fertilizers that contained a relatively large amount of water-soluble phosphorus, the citrate-soluble fraction was partly available.
